United States Patent 3,210,022 AUTGMATIC WINDING MACHINE Winthrop L. Perry, Milford, N.H., assignor to Abbott Machine Co., Inc., Wilton, N.H., a corporation of New Hampshire Original application Sept. 29, 1961, Ser. No. 141,884,

new Patent No. 3,168,257, dated Feb. 2, 1965. Divided and this application May 28, 1964, Ser. No.

7 Claims. (Cl. 242-355 This application is a division of my appliaction Serial No. 141,884, filed September 29, 1961, now Patent No. 3,168,257, for Winding Machine.

One of the objects of the invention is to provide detector-controlled driving mechanism for tending mechanism which can very quickly and reliably institute a cycle of operation of a cam carrier that operates the tending mechanism.

The said application Serial No. 141,884 describes and illustrates all of the several components of two systems of tending mechanism, one of which systems is put into operation whenever a stopped or non-winding unit is presented to detecting mechanism, and other of which systems is put into operation only in case such stopped or non-winding unit lacks a supply end of yarn suitable for tying to the yarn of the package of the unit. The said application Serial No. 141,884 may be referred to for its disclosure of all these components of the two systems. For simplicity, the present application will not again describe in detail all the components of the first system but as to this first system will deal mainly with one of its major components which comes into play early in the cycle of tending, namely the bobbin end carrier mechanism. When the second system operates in case of lack of available yarn, bobbin changing mechanism of this second system also comes into play early in the cycle.

The present application further involves an improvement in bobbin-end carrier mechanism adapting this to operate while a unit which requires tending is taking a step of motion from a position where detection has been made to another position where the package yarn endfinding operation will be performed. This end carrier mechanism is especially adapted not to intefere with the yarn of any properly winding unit traveling past it.

FIG. 250 is a similar view showing the yarn detained and clamped.

FIG. 25D is a similar view showing the hook swing ing down and showing the tail of the yarn as having been pulled out of the slub catcher.

The individual winding units, W, FIG. 1, the rotatable table carrying these and the mechanism for driving the package of each winding unit in a winding direction and the mechanism for driving the package in a reverse direction for end-finding are all shown and described in said application Serial No. 141,884.

The mechanism for stopping winding on any unit upon breakage or exhaustion of yarn is likewise disclosed in Serial No. 141,884, and in the present application FIGS. 2 and 4 which show parts of this mechanism are included principally in order to show two positions of a pin 227, held down in normal winding as in FIG. 2 (against the lifting tendency of a weight-loaded lever 2270, FIG. 5) and somewhat raised in FIG. 4, this latter position being the position assumed by the pin when the unit has been disconnected from its winding-direction driving means.

In FIG. 2 the yarn detector element 65 is up in its running position, where held by the yarn, and an associated lever 66 acts through a link 67 to hold a link 21% out of reach of an oscillating knock-off lever 2410b, an arm 185 which pivots at 186 with the pivotally mounted drive receiving roll now being in an upper position holding up a link 219, causing a lever 229 to bear on the head of the pin 227 and hold this down.

In FIG. 4, the winding unit has been stopped, its drive receiving wheel Edit in a neutral position, its lever 185 forced downwardly (clockwise about the pivot 186) and latched in this position by latch lever 224 engaging a projection 226 on lever 185, the link 219 in this position having swung lever 229 about a pivot 225 to lift it off the pin 227 and allow the pin 227 to rise.

The mechanism whereby the pin 227 is subsequently given further upward movement from its position of FIG. 4 and employed to unlatch the lever 185 and also to move the drive-receiving wheel 180 into drive-receiving relation to the reverse driving mechanism, and subsequently restore the winding unit into operating condition is described in more detail in a further divisional application for automatic winding machine on or about the same date as this application.

The element 231, pivoted at 232 to the latch lever 224 and having a pin 231a extending through a hole 224a in the latch lever is for the purpose of swinging the latch lever 224 in subsequent unlatching of lever 185, this element 231 being idle at the stage when the parts come into the positions of FIG. 4.

Since the machines two systems of tending mechanism are controlled by clutches 24d and 242 respectively and the step-by-step travel of the units is controlled by clutch 241, and these clutches are of peculiar construction, it will be convenient to describe the construction and operation of these clutches before describing their controls.

Referring to FIG. 6 such a clutch, intended to rotate in the direction indicated, may have a pawl carrier element 24-5 having pivoted thereto alternate tail-less and long-tailed pawls 246, 24-7 and 248, 249, the long-tailed pawls having their tails in the trailing direction. The pawls are urged inwardly by spring wires 250 and 251 which interconnect pairs of pawls. The tailless pawls are to prevent overrunning.

A pin carrier element 255, in the simplest case, carries a single pin 256 adapted to be engaged by the forward face of either long-tailed pawl, to be driven thereby. A movable stop element, represented by 258, in the path of the long tail will trip a long-tailed pawl and withdraw it from the pin and declutch the drive. With a single pin 256 and with a single stop element normally in the path of the long tails, the clutch will function as a one revolution clutch. Removing the stop element long enough to allow a pawl to pick up the pin will drive the pin carrier through one revolution.

The clutches referred to as 240 and 242 operate in this manner.

With a second such pin 256a added, with the stop member 25% normally removed from the pawl patch, and with a second stop 253a permanently positioned to trip a pawl at approximately 180 from the position at which a pawl may be tripped by movable stop 258, such a clutch will normally drive continuously. Then if the movable stop member is operated to trip one long-tailed pawl while the other long-tailed pawl is in tripped position in passing the permanent stop 258a, the pin carrier will skip onehalf revolution. The clutch referred to as 241 is uperated in this manner.

The drive to the table 52 is from a motor M2, FIG. 12, through pulley 261, friction drive wheel 262, pinion 263, gear 26 pinion 265, 266 and vertical shaft 270. Shaft 279, FIG. 11, is normally coupled by clutch 241, operated as described above, to a sleeve 27]. which carries oppositely directed crank arm 2'72 carrying Geneva drive rolls 273. These rolls enter the Geneva grooves in the underside of the table 52, each roll 273 advancing the table 30 each time it engages one of the Geneva grooves.

At its bottom end the shaft 270 is connected through bevel gears 289 and 281, FIG. 7, to a sleeve 283 carrying the pawl carrier 245 of clutch 240, the pin carrier 255 of this clutch being fast on a horizontal cam shaft 285. This shaft 285 is operated through the clutch 240 each time that a winding unit requires to be tended, regardless of whether a new bobbin requires to be supplied, this shaft 285 being the cam carrier of the first system of tending mechanism.

The vertical shaft 270 also carries the pawl carrier 245 of the clutch 242, FIG. ll, the pin carrier 255 of this clutch being carried by a sleeve 287 which is rotated through clutch 242 one revolution in those instances in which the bobbin is required to be changed. The sleeve 287 comprises the cam carrier of the second system of tending mechanism.

The sleeve 271 which is driven by clutch 241 carries a cam 29%, FIGS. 11 and 8, against the surface of which a cam-followers roll 291 is yieldingly drawn. As the cam-follower roll moves toward the center of the cam, as permitted by the cam surface, a system of linkage operates. Motion of this linkage can be blocked, short of full movement, by two possibilities, first, by the pin 227 of the winding unit which is at the eleven oclock position being in the depressed position, and second, by yarn being encountered by yarn feeling mechanism. In the first situation, the winding unit is allowed to continue running without the tending mechanism affecting it. In the second situation, where the wnding unit is not running but yarn is present, so much of the tending mechanism as is appropriate to this situation will operate, particularly clutch 245i, shaft 285 and mechanism driven thereby, i.e., the first system of tending mechanism.

In the further situation in which the linkage is not blocked but has its full motion, the additional portions of the tending mechanism concerned with changing the supply bobbin are operated, particularly the clutch 242, sleeve 2%? and parts operated thereby, i.e., the second system of tending mechanism.

Operation of the tending mechanism, either with or without supply of a new bobbin is accompanied by operation of the clutch 241 to skip one-half a revolution of the sleeve 2'71 and Geneva drive, with the result that after the winding unit has been advanced to the twelve oclock position where the tending operations largely take place the table is caused to dwell considerably longer than usual. The skipping of this half revolution also suspends operation of the cam 290 and certain control functions initiated by this cam.

The cam follower 291 is carried by a bell crank 292 having a lug 293, all of which are biased in a clockwise direction, FIG. 8, by a spring 294. At 292a the bell crank is pivotally connected to links 295 and 296. Link 295 serves as a connection to clutch 240. Link 296 serves as a connection to feeler mechanism. Link 2% is pivotally connected at 297 to an arm 298 which is fast on a shaft 299. Shaft 299 also carries a two armed crank 30%) whose opposite ends are connected by links 301, 302 to crank arms 361a, 302a which are fast on shafts 301b, 302b, Arms 3010 and 3920 which are fast on these shafts carry stacks of vertically spaced feeler fingers 301d, 302d which are adapted to intermesh as indicated in FIG. 11.

When a winding unit reaches the eleven oclock position its yarn, if present, extending from its bobbin up to its slub catcher, will lie in the region where these fingers tend to intermesh.

The rotation of cam 290 and the action of spring 294 will tend to allow the arms 3101c and 3d2c to swing from behind the upright of the windnig unit to the position of FIG. 8, and if the fingers encounter no yarn they will intermesh as shown. If the fingers do encounter yarn, the yarn blocks the fingers from intermeshing, this condition being shown in FIG. 9; and the cam follower 291 is prevented from fully following the drop in the contour of cam 290. This condition calls for retying the yarn of the winding unit.

The condition in which the fingers intermesh calls for change of the winding bobbin in addition to tying the end from the yarn package onto the new end of yarn.
